Co-sleeping, bed sharing, or whatever else you want to call it – is an abomination of a behavior that no self-respecting mammal engages in. If you don’t believe me, consider how other mammals handle their kids. You know the old can and string phones we used to make as kids? New chimpanzee parents will string a vine between two empty coconut shell halves, placing one half in the baby chimp’s nest in the next tree over and the other half in the parents’ nest, allowing them to monitor the baby’s cries and activity during the night. If the baby wakes up, they’ll swing on over to the other tree and produce a hairy teat until the little chimp quiets down. Then it’s back to bed. The first thing female voles do after giving birth is dig a separate hole in the ground where the infants will sleep. Same with gophers. Kangaroos are famous for their pouches, which for years researchers assumed the mothers used to keep their infants safe, with easy access to the nipples. But in actuality, the kangaroo pouch is used to store shrubs, grasses, various other edible plants, and boxing gloves, as well as cover up their breasts (kangaroos are incredibly shy and modest creatures).
A few months ago, I addressed the role gender plays in how we respond to intermittent fasting. That post sparked a great discussion, and I’ve since received a fair number of emails from readers eager to learn other ways in which gender plays a role in our health and nutrition. One email in particular set me off on a round of research. So, a hat tip to you, Winifred, for giving me something to think, learn, and write about. I hope everyone finds it to be helpful.
As you may know, women and men store and metabolize fat differently from each other, and a 2008 paper (PDF) reviewed the evolutionary reasons for these differences. Here’s a summary of their findings and few other noteworthy factoids:
Many differences exist between the two sexes. We look different. We sound different. We dress differently from each other. We like different things. Different genres of movies cause men and women to cry (differently). And although society, media, and culture drive and/or inform many of our differences, some are inherent and physiologically-driven. For example, men and women have different biological equipment – both external and invisible to the naked eye – that change how we interact with and respond to our environments, our exercise, our sleep, and our eating habits. Nowhere are these gender differences more evident than in the realm of health and nutrition, and yet it seems that I’ve overlooked a big one: different sex responses to intermittent fasting.
Let’s take a look at a couple recent reader emails:
Hi again, everyone. Thanks for the comments and emails in response to my last post on menopause and hot flashes. I’m working on getting through your questions and hope to do several posts throughout the summer that speak specifically to issues that matter to women. Now that summer is here for most of the country, it seems like a good time to share a frequent reader issue this time of year.
I’m 35 and have been Primal for almost two years now. I’ve always been fairly thin, but going Primal in my eating and exercise has helped me get in better shape and build muscle. Unfortunately, I’m still plagued with some cellulite on the backs of thighs and hips. (Can I mention that I hate swimsuit season?) Why is cellulite so stubborn? Every “miracle cure” I’ve ever tried did next to nothing. Tell it to me straight – will this ever go away? Is there anything I can do? Thanks to you and Mark for everything you do with the Primal community.
Every week I attempt to field at least one reader question in my Dear Mark series of blog posts. Some of the inquiries that are submitted are outside my scope of knowledge or experience, or are questions that are addressed to my wife, Carrie, specifically. While I could (and have been known to) dig into the research on such topics as cellulite, menopause, nursing, giving birth and the like, I think it’s valuable to offer a woman’s perspective on these and related topics of interest. And so, enter Carrie…
Hi, everyone! It’s good to be back on MDA. I so appreciate the emails I regularly get from everyone. Thanks for all your questions and kind messages. I love this community and always enjoy contributing. I get a lot of questions about family and the female perspective in living Primal. One common topic is menopause. I know how intricate a life transition menopause can be, being I’m navigating it myself now. There are a million questions I think women have about menopause, and I know they’ll be more relevant posts coming up. For today, I thought I’d take up one reader’s forum post about hot flashes and sleep. (Do I already see some heads nodding out there?)
